Eight new species of Ecuadorian Ptiliidae are described and figured: Nossidium harrietae sp. nov., Ptenidium robustum sp. nov., P. tauriforme sp. nov., P. triangulum sp. nov., Notoptenidium brunneum sp. nov., Americoptilium nigrescens sp. nov., Discheramocephalus nigerrimus sp. nov. and D. striatus sp. nov. The insects were collected by J. McClarin, 2017–2018, in the Napo Province to the southeast of the capital Quito.
This paper is based on three collections of Ptiliidae from Sarawak totalling more than 2000 specimens made by staff and affiliates of the Natural History Museum, London, between March–July 1978. One new genus Niptella gen. nov with its type species Niptella gutta gen. et sp. nov. and 24 new species are described and figured: Sindosium collinsi sp. nov., Bambara hammondi sp. nov., Bambara subtortuosa sp. nov., Bambara tortuosa sp. nov., Erro brookei sp. nov., Cissidium globulum sp. nov., Cissidium longum sp. nov., Cissidium marshallae sp. nov., Cissidium pauxillum sp. nov., Cissidium subfoveolatum sp. nov., Cissidium triangulum sp. nov., Discheramocephalus nigritus sp. nov., Kuschelidium sarawakense sp. nov., Ptinella alisonae sp. nov., Acrotrichis acuta sp. nov., Acrotrichis belli sp. nov., Acrotrichis bidens sp. nov., Acrotrichis geiseri sp. nov., Acrotrichis globosa sp. nov., Acrotrichis hanskii sp. nov., Acrotrichis muluensis sp. nov., Acrotrichis plaga sp. nov., Storicricha resticula sp. nov., Storicricha umbella sp. nov. New records and information are provided for Dipentium latum Darby, 2019; Ptiliola semitaria Darby, 2018; Baeocrara minima Darby, 2019; Acrotrichis agricola Darby, 2019; Acrotrichis britteni Johnson, 1969; Acrotrichis bubalis Darby, 2019; Acrotrichis cognata (Matthews, 1877) and Acrotrichis cursitans (Nietner, 1856).
Dysponetus is a genus of the family Chrysopetalidae with twelve currently described species. Specimens are fragile and easily damaged or broken during sampling making identification difficult. The most recently described species, Dysponetus joeli Olivier et al., 2012, from the Bay of Biscay and the English Channel, was described from a few small, damaged and poorly preserved specimens. New specimens from the Isles of Scilly, in much better condition, resembled D. joeli except for the absence of ventral cirri on segment 3. Examination of the type material of D. joeli showed it to be identical to these new specimens and highlighted errors in the original description of the species. The present paper corrects the errors and a revised key to species is produced. The differences between D. joeli and the two most similar species, D. bipapillatus Dahlgren, 1996 and D. macroculatus Dahlgren, 1996 are also detailed.
Barail Wildlife Sanctuary (BWS) lies amidst the tropical forests of the state Assam, India between the coordinates 24o58' – 25o5' North latitudes and 92o46' – 92o52' East longitudes. It covers an area of about 326.24 sq. km. with the altitude ranging from 100 – 1850 m. An ongoing study on the group Marchantiophyta (liverworts, bryophyta) of BWS reveals the presence of 42 species belonging to 24 genera and 14 families. Among these, one genus (Conocephalum Hill) and 13 species are recorded as new for the state of Assam, eight species have been found which are endemic to India, seven species are recorded as rare and one species, Heteroscyphus pandei S.C. Srivast. & Abha Srivast. as threatened within the study area. Out of 24 genera identified, 46% have been found growing purely as terrestrials, 25% as purely epiphytes and 29% have been found to grow both as terrestrials as well as epiphytes. Among these, a diverse and interesting range of microhabitats have also been observed for each taxon. It has been found that genera having vast range of microhabitats comprise large percentage of the total liverwort flora of BWS.
This paper provides descriptions of Calcigorgia gorgonians collected from the Sea of Okhotsk and shores of the Kurile Islands between 3 Aug. 1984 and 20 Aug. 1987. New species described are the deep-water gorgonians Calcigorgia matua sp. nov. and C. simushiri sp. nov., belonging to the temperate fauna of the North Pacific hemisphere. Specimens belonging to all species of the genus were examined and the distinctive characters for each one are provided and summarized in a table. A modified diagnosis of the genus is proposed. The finding of a previously undescribed species emphasizes the need of further surveys, particularly in shelf and deeper waters, in order to improve our knowledge of this neglected fauna in Far East seas.
This paper provides descriptions of two new species of Calcigorgia gorgonians collected from the Sea of Okhotsk between 1973 and 2008. The new species are Calcigorgia herba sp. nov. and С. lukini sp. nov., belonging to the deep-water coral fauna of the temperate Northern Pacific. The taxonomy structure of the genus is reviewed and a comparative table is provided for all known species of Calcigorgia. The following taxonomic changes are made: the diagnosis of the genus was corrected from that given in Matsumoto et al. (2019); synonymization of C. simushiri Dautova, 2018 with C. spiculifera Broch, 1935 and inclusion of additional specimens in C. japonica Dautova, 2007 (both performed by Matsumoto et al. 2019) are assumed erroneous. The finding of previously undescribed species emphasizes the need for further surveys, particularly in deeper waters, to improve knowledge of the Octocorallia fauna in Far East seas. The distribution of Calcigorgia (Octocorallia, Acanthogorgiidae) is reviewed and presented based on field and collection studies published since 1935 as well as miscellaneous data from previous literature.

Survey in three protected areas of Chhattisgarh reveals the presence of 50 species of Odonata belonging to 34 genera and 9 families. Specimens were sampled from different lotic and lentic ecosystems. 17 species were exclusively found in or around running water. Larvae or exuviae of 23 species were found and photographed. Habitat availability, larval abundance, species composition and phenology are discussed.
Mangroves of the Indo-West Pacific have remained poorly explored, so even the diversity of the onchidiid slugs, which are some of the most abundant animals in mangroves of the Indo-West Pacific, is not well known. Thanks to several years spent exploring mangroves in the Indo-West Pacific (more than 260 stations), especially in South-East Asia, the diversity of mangrove gastropods can now be addressed through revisions following an integrative taxonomy approach (nomenclature, field observations, comparative anatomy and DNA sequences). A new genus of onchidiid slugs is described, Paromoionchis Dayrat & Goulding gen. nov., which includes five species, three of which are new: Paromoionchis boholensis Dayrat & Goulding gen. et sp. nov., P. daemelii (Semper, 1880) com. nov., P. goslineri Dayrat & Goulding gen. et sp. nov., P. penangensis Dayrat & Goulding gen. et sp. nov. and P. tumidus (Semper, 1880) comb. nov. Paromoionchis gen. nov. is distributed from western India to the subtropical waters of Japan (33° N) and southeastern Australia (33° S). The creation of new taxon names is supported by rigorous nomenclature: the types of all existing species names in the family were examined, the original descriptions carefully studied and nomenclatural issues addressed. The diversity and biogeography of this new genus is discussed in a broader context.
Ostracods belonging to the genus Bennelongia differ much in valve morphology between adults and juveniles. Adult valves are asymmetrical, characterised by a beak-like feature in the anteroventral region of the left valve, and, with some notable exceptions, mostly have smooth or weaklyornamented valves. Juvenile specimens, on the other hand, have valves that are almost symmetrical, with no beak-like feature and are often heavily ornamented. We have examined the last 3 - 4 juvenile stages of 6 Bennelongia species from 5 different lineages, in order to decipher the types of external valve ornamentation and their recurrences during ontogeny and across lineages. It is clear that ornamentation is more prevalent at the early instar stages compared to the last 2 pre-adult stages, and especially when compared to the adult stage itself. We also examined the surprising presence of a calcified inner lamella with a prominent inner list in the pre-adult stages of Bennelongia species, that is usually absent in juveniles of other ostracods, thus questioning if heterochronic processes have provided an intermediate valve morphology between the simple (normal) cypridinid juvenile state and the heavily derived and modifi ed state of adult Bennelongia. We discuss the possible (speculative) functionality of the ornamentation in juveniles.
